changed to ls now corals are dying

[spun710]

Hye guys...on sunday i changed my tank from cc to ls and now my corals, anemones, and snails are all dying...what is going on ...my water paremters are all great and the same as tehy were before the switch...i am getting a new protein skimmer on friday and thats the only thing different i can think of...pleas somebody help

the sand change could have stressed them.

 

[spun710]

but would that cause them all to die off...even my hardy mushrooms and zoos are looking terrible?

hey i was just a platts burgh last week ....i went to 2 lfs's there. where do you work?
ps:if there was something in your water like maybe ammonia(from cc) then you could have sturred it up and released it.get a good skimmer may help.

 

[spun710]

also they were all taken out of the tank to switch over and put back only when tank cleared up a bit...there was no air exposure either

 

[yellowtail]

loom at what i said about ammonia.:thinking:

 

[spun710]

i took all the water out -- no chance in ammonia -- tests show no ammonia in water...i dont know if that tests for the gas though
i work at ***** on mcknight road in pittsburgh

look** what i mean is that your sand bed sucks up bad stuff and you stirring it up (like your not supposed to) can relase bad stuff....how long ago did you do this change?

 

[yellowtail]

there was deffinently stress inflickted during the change.

 

[spun710]

i did not stir up my sand bed... i took all life out before i took cc out...i took all water out in order to get all cc out...put mostly fresh water back in but used a bit of old water as well...there was NO stirring of the sand

 

[spun710]

i agree there was stress but would it be bad enough to kill off all corals?

 

[yellowtail]

well then how was it removed?

 

[spun710]

ok i siphoned water into buckets (without stirring up cc), then my rock and all other organisms were placed in these buckets. I then siphoned out all the water and scooped out the cc. I wiped and dried the tank out before adding the sand. I added fresh saltwater to tank till about 3/4 from the top of the tank... i waited for the tank to clear up a bit then added rock with no corals/"life" on them to speed up the clearing process. After tank cleared fish, corals, and anemones were all readded to tank...at no point did i restir up my sand bed

 

[yellowtail]

that "fresh saltwater" could be at the wrong salinity..............refractometer?also even though you have your cycled rock but not all the fresh saltwater was cycled.,

 

[spun710]

salinity is 1.025 ...i also added water that had been in my tank , and biozyme to get some more bateria introduced quickly

 

[yellowtail]

did you check for nitrIte? you could be going threw a mini cycle.
how much old vs. new water was introduced?

 

[kpk]

What kind of sand did you use? Southdown or something like that it needs to be cured before you add it???

 

[spun710]

southdown and biolive...cured

 

[spun710]

if there was something wrong with the water wouldn t the fish be breathing funny and be dying too?

 

[spun710]

about 5 gallons old to 15 gallons new...could not add too much water -- 5 1/2 inch sandbed
